some intel cpu's only go down to 20%, some down to 10% min state....
so let's do this in lots of 5% to allow for some future cpu's. now
it's not just 0, 25, 50, 75, 100 it's worth making it a real loop to
save on code too. this allows me to actually control the cpu's i see
at the detail level i see they can be controlled at.
so new laptops now seem to no longer support S3 sleep. sleeping is
done basically by going as idle as possible. you can ask the kernel to
freeze execution BUT this seems to use about the same power as staying
alive in my tests. to support this add 2 things:
1. a FREEZE powersave mode which implies we're alive but want to
really stay as idle as absolutely possible.
2. powersave aware sleep functions that replace the usleeps in threads
so they can switch from being super sleepy when in freeze mode to
normal.
on some devices asking the cpu for info like current frequency,
governors etc. seems to be expensive and if done in the mainloop can
block for multiple ms causing framerate hiccups, so move it to a
thread...
Summary:
The intel_pstate scaling driver exposes the `scaling_cur_freq` since
kernel 3.17 [*], it would be fine that the min and max frequencies
are known even without the `scaling_available_frequencie`.
This commit teaches to use the cpuinfo_{min,max}_freq as fallback in
case the `scaling_available_frequencies` is not available within
intel pstate.

When we include support (in the wayland compositor) for compiling with
EGL, the inclusion of the EGL headers cause a conflict with the
Status structure name in this module, so lets rename it.

huge fustercluck commit because there wasn't really a way to separate out the changes. better to just rip it all out at once.
* compositor and window management completely rewritten. this was the goal for E19, but it pretty much required everything existing to be scrapped since it wasn't optimized, streamlined, or sensible. now instead of having the compositor strapped to the window manager like an outboard motor, it's housed more like an automobile engine.
** various comp structs have been merged into other places (eg. E_Comp_Zone is now just part of E_Zone where applicable), leading to a large deduplication of attributes
** awful E_Comp_Win is totally dead, having been replaced with e_comp_object smart objects which work just like normal canvas objects
** protocol-specific window management and compositor functionality is now kept exclusively in backend files
** e_pixmap api provides generic client finding and rendering api
** screen/xinerama screens are now provided directly by compositor on startup and re-set on change
** e_comp_render_update finally replaced with eina_tiler
** wayland compositor no longer creates X windows
** compositor e_layout removed entirely
* e_container is gone. this was made unnecessary in E18, but I kept it to avoid having too much code churn in one release. its sole purpose was to catch some events and handle window stacking, both of which are now just done by the compositor infra
* e_manager is just for screensaver and keybind stuff now, possibly remove later?
* e_border is gone along with a lot of its api. e_client has replaced it, and e_client has been rewritten completely; some parts may be similar, but the design now relies upon having a functional compositor
** window configuration/focus functions are all removed. all windows are now managed solely with evas_object_X functions on the "frame" member of a client, just as any other canvas object can be managed.
*** do NOT set interceptors on a client's comp_object. seriously.
* startup order rewritten: compositor now starts much earlier, other things just use attrs and members of the compositor
* ecore_x_pointer_xy_get usage replaced with ecore_evas_pointer_xy_get
* e_popup is totally gone, existing usage replaced by e_comp_object_util_add where applicable, otherwise just placed normally on the canvas
* deskmirror is (more) broken for now
* illume is totally fucked
* Ecore_X_Window replaced with Ecore_Window in most cases
* edge binding XWindows replaced with regular canvas objects
* some E_Win functionality has changed such that delete callbacks are now correctly called in ALL cases. various dialogs have been updated to not crash as a result

Subject: [E-devel] [e][PATCH] Optimizations v2
Date: Fri, 21 Dec 2012 22:17:32 +0100
Hi,
same patch as before: removed useless nullchecks and
switched some free()'s to E_FREE().
SVN revision: 81592
Hi,
here is a patch for e/src/modules/cpufreq/e_mod_main.c
I. _cpufreq_status_check_available() always returns 1,
so moved to void.
II. Don't need to 'buf[sizeof(buf) - 1] = 0;', as it's
already done by snprintf.
III. Stuff for OpenBSD.
IV. Fixed files descriptors leaks, and removed useless
code.
thanks
